A Detailed History of YLEM
YLEM: ARTISTS USING SCIENCE
YLEM: Artists Using Science and
Technology was started in February, 1981, by Trudy Myrrh Reagan. She
was a studio artist in Palo Alto, CA, painting under the name “Myrrh.”
At an organizing meeting, she explained that many artists gain visibility
and encouragement when they know each other, exhibit together, and exchange
The name “ylem” came from
a physics text. IIt was a name given by George Gamow and colleagues
for the primordial stuff that expanded in the Big Bang to create the
universe. Trudy Myrrh Reagan was motivated and aided by Howard Pearlmutter,
whose Graphic Gatherings at Stanford had introduced her to computer
graphics and its innovators.
YLEM got access to speakers
and use of facilities from Stanford professor Robert McKim, author of
Experiments in Visual Thinking, and graduate student Scott Kim, author
of Inversions. When Trudy Myrrh Reagan met them and and also Pearlmutter’s
friends, she discovered polymaths who loved both the technical and the
artistic, not seeing the division between the two. She had been searching
for such colleagues for ten years.
It was a yeasty time, when
young people at universities and companies knew for certain that what
people were developing there would change the world as we know it. They
and the artists around them were giddy with delight. And the world did
ORIGINAL STATEMENT OF PURPOSE
"Ylem, a non-profit 501 (c) 3 organization, exists to connect art to the driving forces in our culture: science and technology.
"The Florentine Renaissance artists and the Impressionists all knew each other. Ylem exists to create such a community of artists. Studio visits, informal field trips to labs and industry, parties, and discussions forge these friendships. Access to equipment for artists has often resulted.
"The artesian pressure of talent from the group opens up opportunities to exhibit and perform in an otherwise skeptical gallery milieu. Artists in Ylem use technology for positive purposes, and make abstract science ideas more concrete and approachable. They believe in the power of ideas to take form and spread, like the original matter, ylem, from the Big Bang, into the universe we see today.
of merely talking shop about particular techniques, Ylem will explore
the impact of new technologies on society. Will art spread like wildfire
through new media channels like the web? Only if artists train themselves
to use them."
PURPOSE AND PROGRAMS
Ylem (capitalized “YLEM” after
2000) explored the humanistic and peaceful uses to which science and
technology were being put, and exposed both artists and the general
public to research work at both public forums and exhibits.
Field trips were organized to
labs, such as the Holography Institute, NASA and SLAC; industries in
the field of computer graphics—most now defunct; and studios of such
artists as sculptors Bruce Beasley and MIlton Komisar; and prism-light
artists Martha and Alex Nicoloff. It visited Mills College Music Department—an
incubator for early computer music. It visited the San Francisco Garbage
Transfer Station to see artists-in-residence making art from items pulled
out of the trash. Its fifteenth anniversary party was at the home and
holography lab of Cherry Optical.
YLEM had a deliberately comprehensive
approach: Experimental artists in all media, from digital painting to
computer-mediated immersive environments, participated. Artists in traditional
media using science ideas were also welcome. Situated outside academia
and the commercial art world, its artists shared ideas freely and became
great friends. It can’t be emphasized strongly enough that having
fun together made great things possible. It was a unique group in the
early days, had wide appeal, and within five years boasted an international
Several artists changed media
as a result of access to friends who could help them, and knowledge
of new materials. For example, YLEM President Beverly Reiser changed
from designing sculptures with neon and sandblasted mirrors to interactive
art, and web design as well. . Eleanor Kent went from color copier art
to knitting fractal designs, and crocheting electroluminescent (EL)
wire. Helen Golden left photography to embrace large-format digital
painting. Roger Ferragallo, a designer and 3D artist eventually created
a 22-foot-long cosmic digital painting that showed increasing detail
wherever the viewer zoomed inward.
Except for two people who took
care of ongoing clerical work, and intermittent help on publications,
this was an all-volunteer effort. Louis M. Brill, Eleanor Kent,
Beverly Reiser, Larry Shaw, Gary Zellerbach and founder Trudy Myrrh
Reagan spent decades keeping the organization afloat and interesting.
TECHNICAL FRONTIERS AT FORUMS, ON TOURS, AND IN PUBLICATIONS
It was always the quality of imagination
of artists using new technology that was important. One role of YLEM
was to bring new developments to their attention. Its YLEM Forums and Newsletter or Journal
articles, from 1981 to 2008, gave a heads-up about technical advances
useful to them and impacting society as a whole.
1981 - Personal computers: Then, only a few computer kits and devices were available. Amateurs programmed their own. A few artists worked for computer companies developing computer graphics. YLEM Forums treated education and small computers, gave demos of input and output (I/O) devices for art. I/O would be a recurring theme.
1982-4 - computer graphics tours in Silicon Valley.
1982 - Demos of teleconferencing. • Mathematics shown as computer graphic animations. 1983 - In those days, each frame of an animation took 30 minutes or more to compute. Each minute of film has 30 frames. An animator told of his dream of being able to compute facial expressions. • We showed infrared images of dancers, • holograms with animation. • At Stanford, we talked at Stanford with Donald Knuth about his two programs, MetaFont (forerunner to Postscript for font definitions) and TeXt (for page layout, forerunner to PageMaker). • Who? told how he projected the outline of a giant eye onto the TransAmerica Pyramid during the King Tut exhibit. using laser light projection from his friend’s apartment. (The corporation sued, won $1 in damages).
1984 - Biomimicry (then called Bionics).
1985 - Forum demo of 3D TV. • Video synthesizer demo.• First YLEM Newsletter to be produced with new desktop publishing software on the new 128K Macintosh.
1986 - Animated electronic jewelry demo. • An YLEM Journal article by Fred Stitt described the digitization of all media, Xandu, Dynabook; also AI (Artificial Intelligence), VR, (Virtual Reality), and Nanotech.
1987 - Forum talk about NASA’s early experiments in VR. • How Computer Tomography (CT) scans plus Computer Aided Design (CAD) processing become models for surgery.
1988 - Demo of video capture, images output onto cloth. • "Space Bridge" Teleconference of US citizens with ones in the USSR to promote peace.
1989 - December YLEM Newsletter discussed hypermedia, hyperlinks, telepresence, robotics, VR, and expert systems for art. • An art project faxing art to 6 countries involved several YLEM members. • Fractals and art • Demo of interactive art (Mandala Software). 1990 - Discussed avatars and collaborations, telepresence, the International Electronic Cafe. • YLEM Newsletter articles: 1/1990, 2/1990, Optical Character Recognition (OCR) and putting libraries online; • 11/1990, High Definition television (HDTV).
1991 - Forums showed a 3D computer-simulated fly-by of Mars, • discussed VR on home computers
1992 - Field trip to NASA-Ames VR lab.• MIDI music triggered by body signals. • Discussion of camera images, audio recordings that are no longer “proof” (because they can be doctored).
1992, 1993 - Forums on complexity theory and A-Life (Artificial Life: flocking behavior in groups of sculptures).
1994-5 - Forum on networked art, • YLEM and Leonardo/ISAST (International Society for Art, Science, and Technology) join an international collaboration, Jurgen Claus’ Global SolArts Festival. Solar art to be an inspiration for solar energy development. • The internet, developed as a decentralized network for security reasons, by now had become generally available to universities, labs and some businesses. CERN in Geneva, Switzerland, debuted the World Wide Web in 1991. This made the internet very easy to use, and able to send graphic images.
1994-5 - YLEM’s web site, “Art on the Edge, www.ylem.org created. • An YLEM Newsletter article by Fred Lakin
1995 Steve Wilson, “Email Services Lingo” in Nov. '95 declared “The Web grew 220,000% in 1993.” Forums showed art on the web.
1997 - “New Directions in Telepresence,” YLEM Newsletter theme issue in Sept., Eduardo Kac, ed.
1997 - "Nanotech,” March YLEM Newsletter theme issue.
1999 - Forum showed video on biofuel: gas from cooking oil. 199- Forum on sculptures using computer-aided solid modeling with laser deposition prototyping. 2001 - Forum on art inventions at Burning Man draws overflow crowd.
2001 - Cyberarts International X, YLEM’s 20th Anniversary Conference, featured Second Life, Adobe's Atmosphere for 3D computer Graphics; Future theme parks and immersive entertainment; and discussed nanorobots to cure disease. In attendance was Lee Felsenstein, co-founder of Berkeley's Community Memory Project in 1973.
2002 - Forum, The Secrets of Silicon Valley, the first documentary film to note the social impact of high tech: poor health and safety conditions in companies, the need for responsible recycling,; also an example of community empowerment. • “Aesthetic Computing” (artistic forms in formal structures found in software) in YLEM Journal, 9-10/2002. • AI Software described by Dmetri Terzopoulos eliminates much work by technicians in computer animation, Journal, 11-12/2002.

2008 - Building-sized animated LED signs.
FORUMS: SCIENCE AND MATH SUBJECTS
To plan Forums, Trudy Myrrh Reagan
combed science magazines for mention of science advances pioneered by
local researchers and invited them to speak. For instance, in the 1990s,
three prominent astronomers, George Smoot, Joel Primack and Alex Filipenkko,
shared their very recent discoveries with us. Smoot’s COBE satellite
detected radiation in the universe a mere 300,000 years after the Big
Bang. Earlier than that, atoms hadn’t formed, and loose electrons
make it impossible to “see” anything. Primack was using a big chunk
of the supercomputer capacity in the country to test his model of “cold
dark matter” in the early universe. He was trying to solve why
clumps of matter existed, allowing the development of galaxies. Alex
Filipenkko’ measurements turned up the surprising result that the
universe’s expansion appears to be speeding up. Dark Energy was formulated
to explain this effect. Chris McKay, Mars researcher from NASA spoke,
as did Roger Malina, about the Extreme Ultraviolet Explorer Satellite
Mission, and also art in space.
In neuropsychology, Will Gordon
explained the geography of the brain. Roger Shepard at Stanford spoke
on “Paradoxes of Perception” using his Escher-like drawings. Brain
research of particular interest to artists, synesthesia (seeing colors
when hearing or feeling things) was the subject of a Forum in 2001.
YLEM attracted several mathematicians
who did sculpture, among them Helaman Ferguson, Carlo Séquin, and Bathsheba Grossman. Ruth
Asawa could be included as well, for her origami bronzes. All were represented
at YLEM Forums. Math educator and publisher, Dale Seymour, spoke at
its first forum in 1981, and gave one of its final studio visits in
For a geology demonstration, Trudy
Myrrh Reagan deformed and carved into a 10 lb. layer cake, also demonstrated
fluid dynamics with paper marbling. Fluid Dynamicist Milton Van Dyke
from Stanford showed his Album of Fluid Motion. John Greenhill spoke
on Bell’s Theorem in physics. 1987, Robert Langridge showed his computer
models of DNA. The same year, Scott Elrod spoke of IBM’s new tunneling
microscope to see the “outline” of atoms. (who?) demonstrated chemoluminescence. In 2000, a
group from University of Montana spoke of doing art with bioluminescent
bacteria. In 2008, painter Julie Newdoll explained her paintings about
molecular biology, and Luca Cavalli-Sforza used DNA evidence to show
humankind had spread out from a small area in Africa.
FORUMS: ART SUBJECTS BY YLEM ARTISTS
New developments in art were publicized,
for instance, art using networks and remote access; art outside the
art world system, like Cacophony and Burning Man; art using biology,
like Eduardo Kac’s bioluminescent bunny and the “Art Fusion" program at UC Davis combining studio
art and science courses.
Ken Knowlton and Robert Dewar
gave a panel discussion in 1983 on “Finding the Soul in Computer Art.
Humanistic art produced digitally was shown by Lucia Grossberger Morales, Mike
Mosher. Artists Bruce Beasley and Helaman Ferguson showed software designed
especially for them that enabled them to realize difficult ideas they
had for sculptures. Beasley’s technique for casting large scale pieces
in clear Lucite astounded DuPont, who said it couldn’t be done. Dancer/composer/computer
artist Sylvia Pengilly showed her performance videos and demonstrated
transforming her brain waves into music. Ken Goldberg showed his robotic,
telepresence, interactive, online work called The
Stephen Wilson, of San Francisco
State University, regarded art as research, also “keeping watch on
the cultural frontier.” He, Roger Malina of the journal, Leonardo,
ecologist Theodosia Ferguson, Nancy Frank of ArtCom, computer artists
Lucia Grossberger-Morales and Eleanor Kent, and technology writer Louis
M. Brill, associated with Burning Man, helped shape YLEM’s programs.
• The YLEM Newsletter, YLEM Calendar, YLEM Directory of Artists Using Science and Technology and YLEM Journal, helped to validate artists in these fields, undervalued as they were by the rest of the art world, as did its many exhibits.
• The Directory was particularly useful, as it was copiously illustrated with the artists’ works.
• In 1985, David Healy did the first issue of the Newsletter using the new computer graphic design tools.
• Frequently, Louis M. Brill obtained hologram stickers for the covers of the Newsletter. For the twentieth anniversary issue, he obtained a large lenticular, showing an art collaboration of member Dorothy Simpson Krause and her associates in 3D. Nancy Gorglione edited the 15th Annual Newsletter with a hologram she did using a new Polaroid process. Louis obtained four other hologram stickers for it. Volunteers stuck them all in.
• The Journal, edited by Loren
interviews with science fiction writers, conceptual artists, and experimental
EXHIBITS AND EVENTS
Exhibits were curated by Trudy Myrrh Reagan, Beverly Reiser, Eleanor Kent and Barbara Lee. Its six largest exhibits:
• “CreaTech” at Tapestry in Talent, San Jose, CA, in 1983, was a computer art exhibit at the dawn of the personal computer era.
• “Lights On!” 1987, exhibit at Walnut Creek Art Center showed light sculptures. The exhibit traveled.
• “Artists Shedding Light on Science” was an exhibit of science related art at San Francisco State University during the American Association for the Advancement of Science (AAAS) regional meeting in 1994.
• YLEM was invited by Leonardo/ISAST to curate an exhibition for its 30th anniversary at the 111Minna Street Gallery in 1997.
• YLEM’s 20th anniversary exhibit, “The Impact of YLEM,” at SomArts Gallery in San Francisco, displayed 80 artists, ranging from pioneering artists of the 1960s, Ruth Asawa and Ken Knowlton, to two just-completed computer installations by Steve Wilson and Barbara Lee.
• In 2003, the The Blue Room Gallery’s “Interfacing Ideas” included 17 YLEM artists.
• Often, smaller exhibits were
staged at Canessa Gallery in San Francisco run by member Zach Stewart.
• In 1987 it produced Space Ballets, a dance performance by dancer Tina Ebey with digital effects by Beverly Reiser at Walnut Creek Art Center, with the "Lights On!" exhibit, and recorded on the 1989 video, Artists Using Science and Technology.
• In 2001, Robert Gelman organized a wild multimedia musical party for YLEM’s 20th Anniversary, as well as the Cyberarts International X Conference in San Francisco. It took place five days after 9/11. For that reason, the speaker from Brazil was prevented from attending. See "2001" under "TECHNICAL FRONTIERS," above, for the tech advances discussed.
• 2003-2009 - For six years,
the Patterns Study Group, started by Trudy Myrrh Reagan and Shoshanah
